Publication number: 20230155690Abstract: A reflector assembly at a power beam receiver includes at least two sets of reflection surfaces positioned to shift some incoming light away from the center of the beam and towards the periphery. These surfaces may be positioned obliquely to one another, for example orthogonally. By shifting a portion of the power beam away from a higher-intensity center and toward a lower-intensity periphery, the reflector assembly may improve receiver efficiency without substantial redirection of power outside of a power-collecting surface of the receiver.Type: ApplicationFiled: November 11, 2022Publication date: May 18, 2023Inventors: Sergiy DETS, Thomas J. NUGENT, JR.

Concentrator-type photovoltaic (CPV) modules, receiver and sub-receivers and methods of forming same
Patent number: 10416425Abstract: CPV modules include a back plate having an array of 1 mm2 or smaller solar cells thereon. A backplane interconnect network is also provided on the back plate. This backplane interconnect network operates to electrically connect the array of solar cells together. A front plate, which is spaced-apart from the back plate, is provided. This front plate includes an array of primary lenses thereon that face the array of solar cells. The front plate can be configured to provide a greater than 1000× lens-to-cell light concentration to the array of solar cells. To achieve this 1000× lens-to-cell light concentration, the primary lenses can be configured as plano-convex lenses having a lens sag of less than about 4 mm. An array of secondary optical elements may also be provided, which extend between the array of primary lenses and the array of solar cells.Type: GrantFiled: February 9, 2010Date of Patent: September 17, 2019Assignee: X-Celeprint LimitedInventors: Etienne Menard, Christopher Bower, Scott Burroughs, Joe Carr, Bob Conner, Sergiy Dets, Bruce Furman, Matthew Meitl, Michael Sullivan -
Publication number: 20180246617Abstract: The present invention relates to an interactive touch system on a transparent medium and more particularly, the present invention relates to a method and system for improving the contrast of writing on an interactive touch system on a transparent medium. The interactive device has an interactive surface having an interior side and an exterior side. The interior side is observed by at least one emitter and at least one detector. The interactive surface has a privacy layer; the privacy layer transforming between a transparent and a non-transparent state. A processing structure executing instructions detects a pointer contacting the interior side of the interactive surface; and applies a signal to the privacy layer to transform the privacy layer into the non-transparent state.Type: ApplicationFiled: August 31, 2016Publication date: August 30, 2018Applicant: SMART TECHNOLOGIES ULCInventors: Gerald Morrison, Edward Tse, Sergiy Dets, Greg Hartman, Joe Wright, Michael Boyle

Patent number: 9627244Abstract: Apparatuses and methods for supporting a workpiece such as a semiconductor wafer. A support system is configured to support the workpiece while allowing thermally-induced motion of the workpiece, which may include thermal bowing or thermal bending. The system may include a support member having a moveable engagement portion engageable with the workpiece, the engagement portion being moveable to allow the thermally-induced motion of the workpiece while supporting the workpiece. The moveable engagement portion may include a plurality of moveable engagement portions of a plurality of respective support members, which may be resiliently engageable with the workpiece. The support members may include flexible support members each having an unconstrained portion and a constrained portion, and the moveable engagement portions may include the unconstrained portions.Type: GrantFiled: December 19, 2003Date of Patent: April 18, 2017Assignee: Mattson Technology, Inc.Inventors: David Malcolm Camm, Guillaume Sempere, Ljubomir Kaludjercic, Gregory Stuart, Mladen Bumbulovic, Tim Tran, Sergiy Dets, Tony Komasa, Marc Rudolph, Joseph Cibere

Patent number: 9482468Abstract: A first heat-treating method involves monitoring at least one thermal efficiency parameter associated with an irradiance system configured to produce an irradiance flash incident on a surface of a workpiece, and automatically updating control information used by the irradiance system to produce the irradiance flash, in response to the monitoring of the thermal efficiency parameter. A second method involves predicting a heating effect of an irradiance flash to be incident upon a surface of a workpiece, in response to a measurement of a heating parameter of the surface, and pre-adjusting the irradiance flash, in response to the predicted heating effect. A third method involves measuring a temperature of a surface of a workpiece during an initial portion of an irradiance flash incident on the surface, and controlling a power of a remaining portion of the irradiance flash, in response to the temperature.Type: GrantFiled: September 14, 2006Date of Patent: November 1, 2016Assignee: Mattson Technology, Inc.Inventors: David Malcolm Camm, Sergiy Dets, Kevin McDonnell, Greg Stuart, Tilman Thrum, Igor Rudic, Ljubomir Kaludjercic

Patent number: 7398014Abstract: A heating arrangement heats a first major surface of a workpiece with an illumination energy such that a first portion of the illumination energy is directly incident upon the first major surface of the workpiece and a second portion of the illumination energy is directed such that, at least initially, the second portion would miss the first major surface. A reflector, having a central opening, reflects at least some of the second portion of the illumination energy onto the peripheral edge region of the workpiece for preheating compensation. The reflector is configured for shadow-free exposure of a second, opposing major surface of the workpiece to a flash heating energy. A workpiece manipulation arrangement is described to provide for dynamic preheating movement to vary a heating profile across the workpiece and, thereafter, move the workpiece to a flash heating position. Automatic workpiece centering is featured by the manipulation arrangement.Type: GrantFiled: January 12, 2007Date of Patent: July 8, 2008Assignee: Mattson TechnologyInventors: Dave Camm, Mike Krasnich, Miaden Bumbulovic, Sergiy Dets, Steve McCoy
